Professor Emeritus of Electrical Engineering
Interests: Special Relativity Age: 85
Hartwig is interested in special relativity and carried out experiments showing that the relativistic transverse Doppler shift and, hence, time dilation effects are absent. His teaching activities included basic electromagnetism, semiconductor devices and circuits, opto-electronics, wave propagation and relativity.

Research and Teaching Activities
Crystal growth of compound semiconductor materials, bulk semiconductor and hetero-junction devices for microwave and millimeter-wave applications, Gallium-Arsenide integrated circuits, and microwave sensors. He developed the first stable bulk semiconductor amplifier, known as the TEA (transferred electron amplifier), together with co-workers at Bell Labs. As an Emeritus Professor he is now teaching Wave Propagation and Relativity and, Why Relativity is Wrong.
